</div>
<p class="last">These nodes monitor additional parameters such as CO2 or VOC.  As
these parameters tend to be affected by occupancy these nodes are
ideal for deployment in commonly used areas such as the living room, or bedrooms.</p>
</dd>
<dt>Power Monitoring Nodes</dt>
<dd>These nodes are used to monitor the energy
consumption of a property, and need attaching to the electricity
meter.</dd>
<dt>Server Node</dt>

between the network and the server itself.</dd>
